我想給Tomcat 6運行一個Hello World Struts2的項目的Struts2的Hello World JSP示例錯誤
我不斷收到：

不過，我對struts2中的WEB需要的jar -INF/lib文件夾。
罐：
支柱核心 XWork的 OGNL freemarker的 公地文件上傳 的commons-io的 公地郎
任何想法？
我跟着一個網上Struts2的HelloWorld示例：
HelloWorld.action類：
package za.co.vine.tutorialspoint.struts2;
public class HelloWorldAction{
private String name;
public String execute() throws Exception {
return "success";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
的helloWorld.jsp：
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
Hello World, <s:property value="name"/>
</body>
</html>
的index.jsp：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World From Struts2</h1>
<form action="hello">
<label for="name">Please enter your name</label><br/>
<input type="text" name="name"/>
<input type="submit" value="Say Hello"/>
</form>
</body>
</html>
在struts.xml ：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<constant name="struts.devMode" value="true" />
<package name="helloworld" extends="struts-default">
<action name="hello"
class="za.co.vine.tutorialspoint.struts2.HelloWorldAction"
method="execute">
<result name="success">/HelloWorld.jsp</result>
</action>
</package>
</struts>
的web.xml：

打開你的核心jar並檢查這個類：org.apache.struts2.interceptor.SessionAware是否存在於jar中，或者從http://mirrors.ibiblio.org/pub/mirrors/maven2/下載jar文件org/apache/struts/struts2-core/2.0.11.2/struts2-core-2.0.11.2.jar –
給出錯誤的完整堆棧跟蹤。 – Dipak
好吧，我固定的上述錯誤，現在我得到這樣的： java.lang.NoSuchMethodError：com.opensymphony.xwork2.config.ConfigurationManager.addConfigurationProvider（LCOM/OpenSymphony的/ xwork2 /配置/ ConfigurationProvider;）V – lulu88
